Abstract

提供了一种可提高光利用率的三维投影光调制装置，用于立体电影技术领域，其包括：偏振分光棱镜组件、偏振面旋转组件（306；408）、反射镜（302，303；402，403）、透镜组、线偏振器（307，309，312；406，409，411）、偏振调制器（308，310，313；407，410，412）、驱动电路。偏振分光棱镜组件（301；401）将入射光束分为透射光束、上半束反射光束、下半束反射光束；偏振面旋转组件（306；408），将透射光束的偏振面或上半束反射光束、下半束反射光束的偏振态面旋转90度；反射镜（302，303；402，403），用于调整上半束反射光束、下半束反射光束的传播方向；透镜组，用于调整透射光束的大小范围；线偏振器（307，309，312；406，409，411）用于过滤所经过的光束；偏振调制器（308，310，313；407，410，412），将调整后的透射光束、上半束反射光束、下半束反射光束按照帧顺序调制为左旋圆偏振光和右旋圆偏振光。这种装置可有效提高立体电影放映装置的光利用率，同时具有体积小巧，各光束重合简单的优点。
